But it's wrong, and adding # the proper user_access_end() is trivial enough (and doing it for the # other error cases where it isn't needed doesn't hurt). # # I noticed it while doing the same prep-work for changing # user_access_begin() that precipitated the access_ok() changes in commit # 96d4f267e40f ("Remove 'type' argument from access_ok() function"). # # Fixes: fddcd00a49e9 ("drm/i915: Force the slow path after a user-write error") # Cc: Chris Wilson <chris@chris-wilson.co.uk> # Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> # Cc: stable@kernel.org # v4.20 # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 0b2c8f8b6b0c7530e2866c95862546d0da2057b0 # < make -s -j 48 ARCH=x86 O=/kisskb/build/linus_x86_64_defconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- x86_64_defconfig # make -s -j 48 ARCH=x86 O=/kisskb/build/linus_x86_64_defconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- You are building kernel with non-retpoline compiler.
